Staple Holding Strength of Furniture Frame Joints Constructed of Plywood and Solid Wood

Abstract

The withdrawal and lateral holding properties of three types of plywood with one stapled as well as one-row multi-stapled joints were studied and compared. The results show that variations in plywood density have a significant effect on withdrawal strength and a relatively small effect on lateral holding strength. At four staples, the withdrawal strength of the eucalyptus plywood with a density of 0.59 g/cm3 is 1821 N, which is 21% higher than that of poplar plywood with a density of 0.51 g/cm3 at 1498 N and 32% higher than that of eucalyptus/poplar composite plywood with a density of 0.53 g/cm3 at 1275 N. In terms of lateral holding strength, eucalyptus plywood has a lateral holding strength of 1603 N 12% lower than the 1807 N of eucalyptus/poplar composite plywood and 10% lower than the 1761 N of poplar plywood. As the number of staples increased from 1 to 4 in increments of 1, the withdrawal strength of eucalyptus plywood continued to increase, while the nodal strengths of the poplar plywood as well as eucalyptus/poplar composite plywood did not differ significantly between 3 and 4 staples, and there is a significant increase in the lateral holding strength for all three plywood nodes. Equations for predicting the withdrawal and lateral holding strengths of one-row multi-stapled joints were derived separately.

The State of the Art of Biomechanics Applied in Ergonomic Furniture Design

“…Aesthetic design, on the other hand, focuses on the artistic aspects of furniture design, encompassing features such as form, texture, color, and shape, while taking into consideration the influence of relevant cultures or fashion trends, as well as the demands of consumers [2][3][4][5]. Engineering design, which is the last key element of design, is the process of determining the most appropriate ergonomic criteria, materials, construction techniques, and manufacturing technologies [6][7][8][9][10][11][12].…”

Study on the Effects of Selected Factors on the Diagonal Tensile Strength of Oblique Corner Furniture Joints Constructed by Wood Dowel

“…The structure-reinforced method commonly investigates factors influencing the strength of joints used in wood products and proposes new jointing methods to improve them. Among these studies, the strength of furniture joints, especially mortise-and-tenon joints [19][20][21] and wood dowel joints [22][23][24][25][26], occupied a large proportion. By contrast, using the structure reinforced method commonly brings less cost than the modification method and is more environmentally friendly.…”
